I asked my mom what the protocol is for the learning center... it's 1/8 tsp bleach for 16 oz water, which she said is 1 tsp per gallon then. She said soak them for 2 mins, rinse them off, and they're good to go.

Good Luck! I'm so glad Anthony's past the stage of putting things in his mouth... it's a pain to disinfect all the toys!
